Seems to be studying the oil situation.
Looks like you’re right. Here’s the article on NASA’s page. http://www.nasa.gov/topics/earth/features/oil_spill_er2_feature.html
A lot of good information and pictures.
The ER-2 is temporarily working out of Offutt. Had no idea it was here until I saw it fly over this evening.
eesh, I’m getting vertigo just looking at the map.
